(a) In vivo whole-animal imaging of mice bearing subcutaneous HepG2 tumors treated with free DiR and mPEG-Rg3-BSA NPs/DiR with different formulations at 2 h, 8 h, and 24 h and ex vivo fluorescence imaging of dissected organs after 24 h postinjection; (b) quantitative analysis of the fluorescence intensity of DiR in tumor tissue examined using the in vivo imaging system. Values are reported as the for triplicate samples. represents .
